Remarks. Species described from Brazil and known only from the type specimens. In the original description of this species, the authors indicated that its placement in Amblyseius is provisional. The presence of a bifurcate atrium is typical of Graminaseius , whereas the smooth sternal and ventrianal shields and the many teeth on the fixed cheliceral digit is common in Amblyseius .
